  • Patent number: 9027067
    Abstract: System and method for providing a probabilistic order of tiles relative to a current section of a video that a user is viewing. A cache implementation uses this ordering to decide what tiles to evict from the cache, i.e. which tiles will probably not be accessed within a particular timeframe, but not when to evict (this is up to the cache implementation). A cache implementation can also use the prioritized list of the present embodiment to pre-fetch tiles.

  • Publication number: 20150106696
    Abstract: System and method for displaying an encoded standard-formatted image with information including, but not limited to, geospatial information. This information, possibly in mark-up language format, can be quickly accessed and used to modify the image to which it is appended, or it can be ignored because the image itself remains unchanged.

  • Patent number: 8923632
    Abstract: System and method for encoding standard-formatted images with information including, but not limited to, geospatial information. This information, possibly in mark-up language format, can be quickly accessed and this enables the standard-formatted images to be shown in geospatial information systems as map images, while preserving their compatibility with other systems like web browsers and mobile phones.

  • Patent number: 8885980
    Abstract: System for storing and retrieving tiled image data. System and method store a record in an image file for each tile at a zoom level, create a lookup table for the record, store a null value in the lookup table when there are no tile records at the row and the column of the lookup table, omit a row from the lookup table when there are no tile records in the table row, create an index file having a null value for each omitted rows, and retrieve an address for a specific tile by seeking the row associated with the record in the index file, reading a value, positioning the lookup table according to the index value if the value is non-null, seeking the column associated with the record, reading an address associated with the record, and retrieving the tile associated with the record at the address.

  • Publication number: 20140101207
    Abstract: System and method for storing a dataset of image tiles. Method includes determining a number of zoom levels, accessing a cluster file that includes a subset of the zoom levels, and accessing the image tiles. For each of the image tiles, a cluster name is computed. For each of the image tiles, if the cluster file has a name that matches the computed cluster name, an image tile pointer is stored in a fixed length index, and the image tile associated with the computed cluster name is stored. For each of the image tiles, if the cluster file name does not match the computed cluster name, another subset of the zoom levels is computed, a new cluster file is created, an image tile pointer is created and stored, and the image tile is stored associated with the computed cluster name in the new cluster file according to the image tile pointer.

  • Patent number: 8024318
    Abstract: A method and computer system for identifying internet web pages containing documents that comply with a predetermined XML schema. The method includes searching the internet with a search engine for web pages using initial search terms and identifying a first set of HTTP URLs, web crawling at least the first set of HTTP URLs to identify additional HTTP URLs, appending a query to the identified URLs, and evaluating the responses to the query to determine which responses comply with the predetermined XML schema. The XML schema can be a Web Mapping Services schema. The system can store responses that comply with the XML schema in a database of servers, periodically check the database for validity, and convert the map requests for map servers in the database to a GIDB Portal Interface API.

  • Publication number: 20100332192
    Abstract: A data set can self-describe a set of data specifications that describe the physical measurements, spatial representation, and file format of data stored in the data set. A data processing tool can self-describe a set of input specifications of the physical measurements, spatial representation, and file storage format of data that can be accepted for processing by the tool. Fully automated methods for coordinating the processing and analysis of the data set by the data processing tool are presented which ensure that the data input to a data processing tool represents the proper physical measurements, has the proper spatial representation, and is in the proper file format to permit the data processing tool to produce logically correct output.

  • Patent number: 7791616
    Abstract: A method and system for efficiently converting an image from a first map projection to a second map projection image. The method includes precomputing coordinates in the first map projection for a subset of the total number of pixels in an empty second map projection image and subsequently, finding the first map projection coordinates of each of the remaining pixels by linear interpolation using the precomputed first map projection coordinates of the nearest surrounding precomputed pixels. A color is assigned to the second map projection image pixel with bilinear interpolation using color values of surrounding first map projection pixels. If the first map projection has fiducials, only the area within the fiducials is considered. An embodiment converts a USGS DOQ in UTM format into Geodetic coordinates.
